write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first - [Testing Anti Patterns](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-testing-anti-patterns) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-testing-anti-patterns` Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies - [Requesting Code Review](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-requesting-code-review) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-requesting-code-review` Use when completing tasks, implementing major features, or before merging to verify work meets requirements - dispatches superpowers:code-reviewer subagent to review implementation against plan or requirements before proceeding - [Using Zenpowers](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-using-zenpowers) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-using-zenpowers` Use when starting any conversation - establishes mandatory workflows for finding and using ZenPowers skills, including using Read tool before announcing usage, following brainstorming before coding, and creating TodoWrite todos for checklists - [Finishing A Development Branch](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-finishing-a-development-branch) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-finishing-a-development-branch` Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup - [Defense In Depth](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-defense-in-depth) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-defense-in-depth` Use when invalid data causes failures deep in execution, requiring validation at multiple system layers - validates at every layer data passes through to make bugs structurally impossible - [Condition Based Waiting](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-condition-based-waiting) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-condition-based-waiting` Use when tests have race conditions, timing dependencies, or inconsistent pass/fail behavior - replaces arbitrary timeouts with condition polling to wait for actual state changes, eliminating flaky tests from timing guesses - [Root Cause Tracing](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-root-cause-tracing) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-root-cause-tracing` Use when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack, adding instrumentation when needed, to identify source of invalid data or incorrect behavior - [Testing Skills With Subagents](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-testing-skills-with-subagents) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-testing-skills-with-subagents` Use when creating or editing skills, before deployment, to verify they work under pressure and resist rationalization - applies RED-GREEN-REFACTOR cycle to process documentation by running baseline without skill, writing to address failures, iterating to close loopholes - [Writing Skills](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-writing-skills) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-writing-skills` Use when creating new skills, editing existing skills, or verifying skills work before deployment - applies TDD to process documentation by testing with subagents before writing, iterating until bulletproof against rationalization - [Systematic Debugging](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-systematic-debugging) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-systematic-debugging` Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes - four-phase framework (root cause investigation, pattern analysis, hypothesis testing, implementation) that ensures understanding before attempting solutions - [Executing Plans](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-executing-plans) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-executing-plans` Use when partner provides a complete implementation plan to execute in controlled batches with review checkpoints - loads plan, reviews critically, executes tasks in batches, reports for review between batches - [Brainstorming](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-brainstorming) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-brainstorming` Use when creating or developing anything, before writing code or implementation plans - refines rough ideas into fully-formed designs through structured Socratic questioning, alternative exploration, and incremental validation - [Using Git Worktrees](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-using-git-worktrees) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-using-git-worktrees` Use when starting feature work that needs isolation from current workspace or before executing implementation plans - creates isolated git worktrees with smart directory selection and safety verification - [Writing Plans](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-writing-plans) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-writing-plans` Use when design is complete and you need detailed implementation tasks for engineers with zero codebase context - creates comprehensive implementation plans with exact file paths, complete code examples, and verification steps assuming engineer has minimal domain knowledge - [Receiving Code Review](https://agentstack.voostack.com/l/skill-alexsandrocruz-zenpowers-receiving-code-review) — Skill · Free · security-reviewed — `agentstack add skill-alexsandrocruz-zenpowers-receiving-code-review` Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable -
